Brand x copier has improved its copier so that it produces 10% more copies than its old model. if the old model ran 420 copies per hour, how many copies would the new model run? round your answer to the nearest whole number. a. 221 copies per hour c. 462 copies per hour b. 435 copies per hour d. 447 copies per hour

Hello!

to solve this, do the following equation:
x=brand x copier
y=old version

x=y+(y*.1)  or  x=y*1.1

using either of these equations, the math I will show will get you the correct answer

462=420+(420*.1)  or  462=420*1.1

your final answer is:  the new copier produces 462 copies per hour

I hope this helps, and have a nice day!
